Is this valid or a scam?  I've been getting a recorded message every Wed at 8pm.  I've never worked in Iowa.

Iowa Dept of Revenue - leaves an almost impossible to understand message saying to call them.  Never worked in Iowa, don't ever go there...except to see the KISS concert!

Since the Dept of Revenue weather state or federal do not call you they use the U.S. mail I'd say it's a scam.
